Entry Door Replacement: What to Consider
TL;DR: Replacing your home’s front entry door costs $1,200-$5,000 installed for a standard 36-inch fiberglass or steel pre-hung door, and $3,000-$10,000+ for premium wood or large multi-panel entry systems. Quality entry doors last 25-50 years. Top brands: Therma-Tru, Pella, Andersen, JELD-WEN, ProVia. Insert installation in a sound existing jamb is a confident weekend DIY project; full-frame replacement and door sizing changes are typically pro jobs. Energy Star rated doors qualify for federal tax credit (up to $250 per door, $500 per home through 2032).
What Is Entry Door Replacement?
An entry door system is the full assembly: door slab (the panel itself), jamb (the wood or metal frame surrounding the door), threshold (sill at the bottom), weatherstripping, hardware (hinges, lockset, deadbolt), and optional sidelites (narrow windows beside the door) and transom (window above). Pre-hung doors include the slab in the jamb, factory-assembled and ready to install. Slab-only replacements drop into an existing jamb.
How Much Does Entry Door Replacement Cost?
A standard 36-inch fiberglass entry door costs $400-$1,500 for the slab or $700-$2,000 for the pre-hung assembly. Installation labor is $400-$1,500 depending on whether it is insert (existing jamb) or full-frame replacement. Total installed: $1,200-$5,000 for standard, $3,000-$10,000+ for premium with sidelites or oversized opening.
| Door Type | Material Cost | Total Installed |
|---|---|---|
| Steel pre-hung 36 in | $200-$600 | $700-$2,000 |
| Fiberglass pre-hung 36 in | $400-$1,500 | $1,200-$3,500 |
| Solid wood pre-hung 36 in | $800-$3,000 | $2,000-$6,000 |
| Pre-hung with sidelites and transom | $1,500-$5,000 | $3,500-$10,000 |
| Pivot or multi-panel custom entry | $3,000-$10,000 | $6,000-$25,000 |
How Long Does Entry Door Replacement Last?
Quality fiberglass entry doors last 30-50 years (no rot, no rust, dimensionally stable). Steel doors last 25-40 years; the skin can dent and rust where finish is compromised. Solid wood doors last 30-100+ years with finish maintenance every 3-7 years; neglected wood doors fail at 15-25 years. Hardware (hinges, lockset, weatherstripping) typically needs replacement every 10-20 years independently of the door itself.
Can I DIY Entry Door Replacement?
Insert replacement of a pre-hung door in a sound existing jamb is a strong DIY project. Plan 4-8 hours: remove the old slab from hinges, transfer the lockset and deadbolt holes (if the new slab is a slab-only purchase), shim the new slab to fit the jamb, set the hinges, install hardware. The most common DIY error is failing to plane the new slab to match the existing jamb dimensions; modern slabs come in standard sizes but field-fit work is often needed.
Full-frame pre-hung replacement and door size changes typically require a finish carpenter or contractor. Removing the existing jamb, prepping the rough opening, setting and shimming the new pre-hung unit, and flashing and caulking the exterior all take experience. Plan $400-$1,500 in labor on top of the door cost.

| JELD-WEN | IWP Aurora | Solid wood | $2,500-$7,000 |
When Should I Replace or Upgrade Entry Door Replacement?
Replace your entry door when: visible daylight at the perimeter despite intact weatherstripping (warped slab or jamb), wood rot at the threshold or jamb base, paint or finish issues on a fiberglass door indicate the gel coat has failed, the slab has bowed and no longer closes flat against weatherstripping, security upgrade (older slab doors below 1-3/4 inch thickness are not secure), or aesthetic update. Energy upgrades alone justify replacement if your existing door is older than 25 years.
Fiberglass vs steel vs wood: which entry door is best?
Fiberglass is the modern best-in-class: dimensionally stable, no rust, no rot, holds finish well, and offers the broadest style range. Steel is the cheapest and most secure (kick-resistant) but dents and rusts where the finish is broken. Wood is the most beautiful and customizable but requires the most maintenance.
Do I need a door with sidelites?
Aesthetic, not functional. Sidelites add 6-18 inches of glass beside the door, brightening the foyer. They cost $400-$1,500 each additional and slightly reduce R-value at the entryway. For traditional and craftsman style homes, sidelites are typical; for modern flush doors, often omitted.
How energy efficient are new entry doors?
An Energy Star certified fiberglass or insulated steel door has a U-factor of 0.20-0.30, comparable to a triple-pane window. Compared to a pre-1990 wood door with weatherstripping issues, an upgrade can save $50-$200 per year in heating and cooling at the entry. Federal tax credit (Section 25C) covers 30% up to $250 per door, $500 per home through 2032.
Will the existing lockset and deadbolt fit a new slab?
Generally yes for standard 36 by 80 inch slabs with 1-3/4 inch thickness, but verify backset (typically 2-3/8 or 2-3/4 inches) and hole prep (single bore or double bore). Slabs from major manufacturers come pre-bored for standard locksets. Smart locks may require a specific hole spacing; verify before ordering.
